environmental hazard assessment for (fresh-) water organisms and
sediment habitats is supported by several acute studies (pelagic
compartment) and by using scientific argumentation (sediment dwelling
environmental hazard assessment of the registered substance acute
toxicity studies for freshwater fish, acute and chronic data are
available for daphnids and freshwater algae from a read across
substance. Furthermore STP microorganisms are available for a read
across substance. Long-term studies for fish are waived. Experimental
information about toxicity on marine organisms is not available.
short-term EC50/LC50 values for fish, Daphnia, algae and microorganisms
were 1.96,4.9, > 100 and 14 mg/L, respectively. Chronic data for
daphnids and algae are 0.15 and 8.7 mg/L, respectively.
the most sensitive trophic level with an acute LC50 of 1.96 mg/L. For
daphnids a chronic EC10 of 0.15 mg/L was obtained. This value will be
used as worst case scenario for the risk assessment of aquatic organisms.
